Columnar cell lesions (breast)

Columnar cell lesions of the breast comprise a wide range of breast lesions which are commonly characterized by columnar cells lining the terminal ductal and lobular unit. These range from lesions that show little or no cytologic or architectural atypia to those that show sufficient cytologic and architectural features to warrant a diagnosis of atypical ductal hyperplasia or ductal carcinoma in situ (DCIS).

Entities that fall under this group include

• columnar cell change (CCC) in breast
• columnar cell hyperplasia (CCH) in breast
• columnar alteration with prominent apical snouts and secretions 
• DCIS with columnar cell features
